Description
本発明は、テイクアウトカートン用紙とそれを用いて作製したテイクアウトカートンに関するものであり、特には、吸油性、耐油性、通気性を合わせ持ったテイクアウトカートン用紙とそれを用いて作製したテイクアウトカートンに関する。 The present invention relates to a take-out carton paper and a take-out carton produced using the take-out carton paper, and more particularly to a take-out carton paper having both oil absorption, oil resistance and air permeability and a take-out carton produced using the same.
従来、コロッケ、シュウマイを始めとする揚げ物用などのテイクアウトカートンに使用するテイクアウトカートン用紙には、耐油剤としてフッ素系耐油剤が使用されてきた。しかし、近年フッ素系薬剤は、それを用いて製造した用紙を１００°Ｃ以上に加熱するとフッ素系炭化水素が発生することが分かってきた。 Conventionally, fluorinated oil-proofing agents have been used as oil-proofing agents in take-out carton papers used in take-out cartons for fried foods such as croquettes and shumai. However, in recent years, it has been found that fluorocarbons are generated when a fluorochemical is heated to 100 ° C. or higher.
フッ素系炭化水素は自然界において難分解性であり、自然界（人体内においても）に蓄積する。しかしフッ素系耐油剤は紙に漉き込んで中間層に用いることができ、一種類の紙で吸油性と耐油性の二つの機能を持たせることが可能であった。また、フッ素系耐油剤は被膜にならないので出来上がった紙は通気性を有する。以上のような性質を利用して多くのテイクアウトカートンでフッ素系耐油剤を用いた耐油紙が多く利用されてきた。 Fluorinated hydrocarbons are hardly decomposable in nature and accumulate in nature (also in the human body). However, the fluorine-based oil proofing agent can be used in the intermediate layer by being put into paper, and one type of paper can have two functions of oil absorption and oil resistance. Further, since the fluorinated oil proofing agent does not form a film, the finished paper has air permeability. Taking advantage of the above properties, many take-out cartons have used oil-resistant paper using a fluorinated oil-resistant agent.
フッ素系耐油剤に代わる耐油剤として、アクリル系耐油剤、ポリエステル系耐油剤、澱粉系耐油剤などが紙にコーティング塗工で使われているが、いずれも被膜化しているため、紙の表面にしか使用出来ず、また、中間層に使用することもできなかった。 Acrylic, polyester, and starch-based oil-resistant agents are used as coatings instead of fluorine-based oil-proofing agents in paper coatings. However, it could not be used for the intermediate layer.
また、被膜化しているためカートンに加工する際の罫線加工部分ではクラックが入り易く、その部分のみ耐油性がなくなってしまうという問題もあった。 Further, since the film is formed, cracks are likely to occur in the ruled line processed portion when processing into a carton, and there is also a problem that only that portion loses oil resistance.
本発明は、テイクアウトカートン用紙とそれを用いて作製されたテイクアウトカートンに関する以上のような問題に鑑みてなされたもので、フッ素系薬剤を使用せずに、吸油性、耐油性、通気性を合わせ持ったテイクアウトカートン用紙と該テイクアウトカートン用紙を用いて作製したテイクアウトカートンを提供することを課題とする。 The present invention has been made in view of the above problems relating to take-out carton paper and take-out carton produced using the same, and combines oil absorption, oil resistance, and air permeability without using a fluorine-based chemical. It is an object to provide a take-out carton sheet and a take-out carton produced using the take-out carton sheet.
本発明の請求項１の発明は、片面あるいは両面が無サイズ層になっている中芯紙にプレスによりフッ素系薬剤を除く耐油剤を含浸加工した耐油剤含浸加工紙を波形に成形し、該波形に成形した耐油剤含浸加工紙の一方の面に表ライナー用紙の裏面を対向させて、形成された各段頂と表ライナー用紙の裏面とを耐水糊を介して貼り合わせ、前記耐油剤含浸加工紙のもう一方の面は裏ライナー用紙の裏面を対向させて、形成された各段頂と裏ライナー用紙の裏面とを耐水糊を介して貼り合わせたことを特徴とする、テイクアウトカートン用紙である。 According to the first aspect of the present invention, an oil-resistant impregnated processed paper obtained by impregnating an oil- resistant agent excluding a fluorinated chemical by pressing on a core paper having a non-size layer on one or both sides is formed into a corrugated shape. The back surface of the front liner paper is opposed to one side of the oil resistant agent impregnated processed paper molded into a corrugated shape, and each formed top and the back surface of the front liner paper are bonded together with water resistant glue to impregnate the oil resistant agent. The take-out carton paper is characterized in that the other side of the processed paper faces the back side of the back liner paper, and each formed top and the back side of the back liner paper are bonded together with waterproof glue. is there.
このように請求項１記載の発明によれば、片面あるいは両面が無サイズ層になっている中芯紙にプレスによりフッ素系薬剤を除く耐油剤を含浸加工した耐油剤含浸加工紙を波形に成形し、該波形に成形した耐油剤含浸加工紙の一方の面に表ライナー用紙の裏面を対向させて、形成された各段頂と表ライナー用紙の裏面とを耐水糊を介して貼り合わせ、前記耐油剤含浸加工紙のもう一方の面は裏ライナー用紙の裏面を対向させて、形成された各段頂と裏ライナー用紙の裏面とを耐水糊を介して貼り合わせているので、各ライナー用紙と耐油剤含浸加工紙が内容物から発生する水蒸気により剥離することがない。裏ライナー用紙を通過した蒸気は、波形の耐油剤含浸加工紙の間の空間に達し、段繰り方向に逃げて行きライナーに湿気がこもらない。耐油剤含浸加工紙が存在しているため耐油性を有する。 Thus, according to the first aspect of the present invention, the oil-resistant agent-impregnated processed paper, which is impregnated with the oil- resistant agent excluding the fluorine-based chemicals by pressing, is formed into a corrugated shape on the core paper having one or both sides of the non-size layer. And the back surface of the front liner paper is opposed to one side of the oil-resistant agent-impregnated processed paper formed into the corrugated shape, and the formed tops and the back surface of the front liner paper are bonded together with water-resistant glue, The other side of the oil-resistant agent-impregnated processed paper faces the back side of the back liner paper, and each formed top and the back side of the back liner paper are bonded together with water-resistant glue. The oil-resistant agent-impregnated processed paper does not peel off due to water vapor generated from the contents. The steam that has passed through the back liner paper reaches the space between the corrugated oil-resistant impregnated paper, escapes in the feeding direction, and does not accumulate moisture in the liner. It has oil resistance due to the presence of oil-impregnated paper.
また、請求項２の発明は、請求項１の発明において、前記もう一方の面に位置する裏ライナー用紙が無サイズ紙であることを特徴とする、テイクアウトカートン用紙である。
The invention of claim 2 is the takeout carton paper according to the invention of
このように請求項２記載の発明によれば、もう一方の面に位置する裏ライナー用紙が無サイズ紙であるので、内容物から発生する余分な水分を吸収して、水分が内容物である食品に戻ることを防ぐ。 Thus, according to the second aspect of the present invention, since the back liner paper located on the other side is a non-size paper, it absorbs excess water generated from the contents and the water is the contents. Prevent returning to food.
また、請求項３の発明は、請求項１の発明において、前記もう一方の面に位置する裏ライナー用紙が、撥水処理した用紙であることを特徴とする、テイクアウトカートン用紙である。 According to a third aspect of the present invention, there is provided a take-out carton paper according to the first aspect of the invention, wherein the back liner paper located on the other side is a water-repellent paper.
このように請求項３記載の発明によれば、もう一方の面に位置する裏ライナー用紙が、撥水処理した用紙であることにより、蒸気は裏ライナー用紙を通過するので、内容物である食品が裏ライナー用紙に付着することがない。 Thus, according to the third aspect of the present invention, since the back liner paper located on the other surface is a water-repellent paper, the steam passes through the back liner paper. Will not adhere to the back liner paper.
また、請求項４の発明は、請求項１、２又は３の発明において、耐油剤含浸紙の波形がマイクロフルート形状に成形されていることを特徴とする、テイクアウトカートン用紙である。 According to a fourth aspect of the present invention, there is provided a takeout carton paper according to the first, second or third aspect, wherein the corrugated oil-resistant agent-impregnated paper is formed into a microflute shape.

また、請求項５の発明は、請求項１〜４のいずれか１項記載のテイクアウトカートン用紙を用いて作製したテイクアウトカートンである。
The invention of claim 5 is a take-out carton produced using the take-out carton paper according to any one of
このように本発明のテイクアウトカートン用紙を使用することにより、吸油性、耐油性、通気性を合わせ持ったテイクアウトカートンを作製することができる。 In this way, by using the takeout carton paper of the present invention, a takeout carton having oil absorption, oil resistance, and air permeability can be produced.
本発明のテイクアウトカートン用紙を一実施形態に基づいて以下に詳細に説明する。 The take-out carton paper of the present invention will be described in detail below based on one embodiment.
本発明のテイクアウトカートン用紙は、例えば、図１に示すように、耐油剤を含浸加工した耐油剤含浸加工紙（１０）をダンボールにおける中芯のように波形に成形し、該波形に成形した耐油剤含浸加工紙の一方の面に表ライナー用紙（１１）の裏面を対向させて、形成された各段頂（ａ，ａ，…）と表ライナー用紙の裏面とを耐水糊を介して貼り合わせ、前記耐油剤含浸加工紙のもう一方の面は裏ライナー用紙（１２）の裏面を対向させて、形成された各段頂（ｂ，ｂ，…）と裏ライナー用紙の裏面とを耐水糊を介して貼り合わせた構造を有している。 For example, as shown in FIG. 1, the takeout carton paper of the present invention is obtained by forming an oil-resistant agent-impregnated paper (10) impregnated with an oil-resistant agent into a corrugated shape like a core of a corrugated cardboard, and forming the oil-resistant material into the corrugated shape. The back side of the front liner paper (11) is made to face one side of the agent-impregnated processed paper, and the formed tops (a, a,...) And the back side of the front liner paper are bonded together with water-resistant glue. The other side of the oil-resistant agent-impregnated paper is opposite to the back side of the back liner paper (12), and the formed tops (b, b,...) And the back side of the back liner paper are coated with water resistant glue. It has the structure bonded together.
耐油剤含浸加工紙（１０）は、中芯原紙で少なくとも薬剤を含浸塗工する側は無サイズの薬剤が含浸し易い設計にしておき、その面からサイズプレス、キャレンダープレス、ディッピング＆スクィーズ等の公知の手法で耐油薬剤を含浸加工して、紙の層で１層あるいは２層以上に耐油性をきかせる。こういう手法をとることにより波形加工時の熱やシェアでクラックやピンホールが開かない耐油層が形成される。 The oil-resistant agent-impregnated processed paper (10) is a core base paper that is designed to be easily impregnated with non-size chemicals on at least the side impregnated with chemicals. From that side, size press, calendar press, dipping & squeeze, etc. The oil resistance agent is impregnated by a known method, and the oil resistance is applied to one or more layers of paper. By adopting such a method, an oil-resistant layer is formed in which cracks and pinholes are not opened by heat and shear during waveform processing.
耐油薬剤としては特に限定せず、アクリル系、ポリエステル系、澱粉系、変性澱粉系、メチルセルロース系、あるいはそれらの誘導体を少なくとも１種または２種以上を含んだ
ものが挙げられる。さらに補助剤として硬化剤、架橋剤等を添加しても良い。
The oil-resistant agent is not particularly limited, and examples thereof include those containing at least one or more of acrylic, polyester, starch, modified starch, methylcellulose, or derivatives thereof. Furthermore, you may add a hardening | curing agent, a crosslinking agent, etc. as an adjuvant.
表ライナー用紙（１１）は、容器に組み立てた際、表面側に位置するため、美粧印刷を施す場合には表面にクレイコート層などが塗工されていることが望ましいが、そうでない場合には特に限定されない。 Since the front liner paper (11) is located on the front side when assembled into a container, it is desirable that a clay coat layer or the like is applied to the surface when performing cosmetic printing, but otherwise There is no particular limitation.
また、出来上がったテイクアウトカートン用紙として望ましい坪量は、３０〜３００ｇ／ｍ2 程度である。坪量が３０ｇ／ｍ2 未満の場合は、波形に段繰りした後、容器の組み立てた場合、表側に皺が多く発生して見栄えが悪くなり、坪量が３００ｇ／ｍ2 を超えると、テイクアウトカートンとしては高坪量になってしまい経済的でない。 A desirable basis weight of the finished take-out carton paper is about 30 to 300 g / m 2 . If the basis weight is less than 30 g / m 2 , after assembling into a waveform, when assembling the container, a lot of wrinkles are generated on the front side and the appearance deteriorates. If the basis weight exceeds 300 g / m 2 , take-out A carton is not economical because it has a high basis weight.
裏ライナー用紙（１２）は、容器に組み立てた場合、収容される内容物が直接触れる面で、内容物の特性によって用紙は選択可能で、代表的にはライナー用紙を用いる。坪量は１０〜２００ｇ／ｍ2 程度が望ましく、坪量が１０ｇ／ｍ2 未満だと波形に段繰るコルゲート加工が難しくなり、また、坪量が２００ｇ／ｍ2 を超えると経済的ではなくなる。 When the back liner paper (12) is assembled in a container, it can be selected depending on the characteristics of the contents, and the liner paper is typically used. The basis weight is preferably about 10 to 200 g / m 2, the basis weight becomes difficult corrugating coming stage waveform and less than 10 g / m 2, The basis weight is not economical if it exceeds 200 g / m 2.
コロッケのように水分が多い内容物を収容するような用途に使用する場合には、裏ライナー用紙（１２）に無サイズ用紙を用いて、水分を吸い取り、食品に戻ることを防ぐ。 In the case of using the contents containing a lot of moisture such as croquettes, non-size paper is used as the back liner paper (12) to absorb moisture and prevent returning to food.
また、餃子やシュウマイのように内容物が紙にくっつき易い食品を収容するような用途に使用する場合には、裏ライナー用紙（１２）は撥水処理を施した用紙を用いて、蒸気を通すことにより内容物が紙にくっつかないようにする。 In addition, when used for applications such as dumplings or shumai where the contents are likely to stick to paper, the back liner paper (12) uses water-repellent paper and passes steam. This prevents the contents from sticking to the paper.
つぎに、本発明のテイクアウトカートン用紙の製造方法の一実施例を示す。 Next, an embodiment of the method for producing take-out carton paper of the present invention will be shown.
まず、無サイズ紙または片面あるいは両面が無サイズ層になっている中芯紙に耐油剤をサイズプレス等の方法により含浸させて耐油剤含浸加工紙（１０）を作製する。別に表ライナー用紙（１１）と裏ライナー用紙（１２）を準備する。 First, an oil-resistant agent-impregnated processed paper (10) is produced by impregnating a non-size paper or a core paper having one or both sides of a non-size layer with an oil-resistant agent by a method such as a size press. Separately, a front liner paper (11) and a back liner paper (12) are prepared.
耐油剤含浸加工紙（１０）は、ダンボール作製の際の中芯原紙に相当し、マイクロフルート製造用コルゲータにより、耐油剤含浸加工紙（１０）を中芯にして一方の面に表ライナー用紙（１１）を、もう一方の面に裏ライナー用紙（１２）を貼合した、図１に示すようなテイクアウトカートン用紙（１）を作製する。なお、この際、耐水性の耐水糊を用いることにより、内容物の蒸気により接着している段頂部分が剥離することを防止できる。 The oil-resistant agent-impregnated processed paper (10) corresponds to a core base paper for corrugated cardboard production, and a corrugator for producing microflutes produces a surface liner paper (on one side) with the oil-resistant agent-impregnated processed paper (10) as a core. 11), a takeout carton paper (1) as shown in FIG. 1 is prepared by pasting the back liner paper (12) on the other side. At this time, by using a water-resistant water-resistant paste, it is possible to prevent the top portion bonded by the vapor of the contents from peeling off.
こうして作製したテイクアウトカートン用紙（１）から、一般的に公知の方法によりブランク（３０）を打ち抜き、テイクアウトカートンを作製することができる（図２（ａ）、（ｂ）参照）。 From the take-out carton paper (1) thus produced, a blank (30) can be punched out by a generally known method to produce a take-out carton (see FIGS. 2A and 2B).
